Embodiment Construction
[0030] Such as figure 1 Shown, the inventive method realizes steps as follows:
[0031] 1. Establish camera coordinate system, image coordinate system, target coordinate system and laser tracker coordinate system.
[0032] Such as figure 2 As shown, establish the camera coordinate system O C -X C Y C Z C , where O is the coordinate origin, XYZ is the direction of the three coordinate axes, the same below; the laser tracker coordinate system O T -X T Y T Z T , the target coordinate system O W -X W Y W Z W , the coordinate system of the laser tracker after rotation is O TR -X TR Y TR Z TR , is the coordinate system O W -X W Y W Z W to coordinate system O C-X C Y C Z C the rotation matrix of is the coordinate system O W -X W Y W Z W to coordinate system O C -X C Y C Z C the translation matrix of is the camera coordinate system O C -X C Y C Z C to coordinate system O TR -X TR Y TR Z TR the rotation matrix of is the camera coordinate...
